1. An energy storage device, comprising:

  • an array of electrochemical cell elements;

    a containment lattice member surrounding the electrochemical cell elements and including void spaces between and around the electrochemical cell elements, the void spaces containing a first phase change material in thermal contact with the electrochemical cell elements;

    a second containment lattice member adjacent to the containment lattice member, and including further void spaces containing a second phase change material in thermal contact with the first phase change material;

    an air flow space separating the containment lattice member and the second containment lattice member, thereby also separating the first phase change material and the second phase change material; and

    a heat exchanger disposed in the air flow space and connecting the first phase change material and the second phase change material, wherein the heat exchanger provides the thermal contact, and the air flow space is open at two ends to receive an air flow over or through the heat exchanger.
